I have the same issue on the galaxy nexus. Power button press turns the screen off a second then it's back on again. Random issue, recovery mode factory reset doesn't fix the problem.

Commonly referred to SOD or sleep of death, search the forums next time.

Can you tell me how to do it without screen?
keep pressing power + volume down button.
You will enter the bootloader. and You will find the option of factory reset there.
Don't leave the button even after phone restarts.

Had the same problem. It was the motherboard, so they had to replace it
Just take the phone to HTC repair.
I have a Samsung Galaxy SII with CM9 installed. About a week ago, the power button stopped working, or at least started behaving erratically. The power button could not be used to wake the phone up or put it to sleep, and if took the battery out and put it back in it would begin booting immediately. I don't think it did this before. I think that the power button is stuck in a way that the phone always reads at as being pressed though I am not sure. When I press the button it still clicks and feels like it did before. Yesterday when I rebooted the phone, and it hung on the bootup screen for CM9. The animation didn't loop, it just froze. I would like to revert back to the stock ROM so that I can send the phone in for a warranty repair, but I can't keep it in download mode because the power button is constantly pressed, causing it to reboot. Is there any way to keep the phone in download mode with the power button pressed so that I can revert back to the stock rom? I have a jig but it doesn't seem to work with the power button pressed. Thanks.
What happened is that i opened an app and then the phone went to sleep, when I unlocked it the screen started to glitch and appear to pressing on the screen for itself. I tried pressing the home button but it was lagging and nothing really happened so I held down the power button and reset the phone. When the phone booted back up and I had to enter my screen lock, I noticed that it wasn't corresponding with where I was pressing, also I pressed on the screen with a quick touch, it appeared that multiple touches registered all over the screen. Since I couldn't get past the screen lock, I turned off the phone, went into Recovery and factory reset the phone. Even after the factory reset, the problem persists so I can't even go through the setup wizard. The phone is completely stock by the way, is there any way to fix this? Or am I going to have to send it back?
Samsung Galaxy A50 does not turn on after factory reset. Only from recovery. (Power and Volume up and select reboot). Do you have anyone similar problem please?
Factory Reset I repeated 2x. I did Wipe. I have also done the Software reset. I still can't turn on the Power button...
EDIT: When I connect charging, the POWER button works. However, the battery is charged at 100%.
EDIT2: The Samsung phone can only be switched on by double pressing the power button. First press: Picture of the round charge. Press the POWER button a second time after the picture goes blank. Now the phone goes on. Do you have it, too?
That's weird. I've never heard of that happening. I think you may have recieved a faulty unit.
